Our vertical storm windows mount over double-hung openings to cut air infiltration, dampen outside sound, and shield primary glass from the elements. Every unit is fabricated from powder-coated aluminum to your exact width and height. Pick a dual-rail model for straightforward performance or step up to the three-rail design for independent top-and-bottom ventilation and maximum weather protection.
Frequently Asked Questions
Common questions related to this collection keyword and buying intent.
What makes vertical storm windows a smart investment?+
They add a sealed air pocket over your existing window, which limits heat transfer, softens exterior noise, and extends the life of original sashes and glazing.
How do dual-rail and three-rail vertical storm windows compare?+
Dual-rail units carry two panels and one screen — a practical, cost-effective choice. Three-rail units add a third track so you get two independent screens and finer airflow control.
Will vertical storm windows help with drafty older homes?+
Absolutely. The perimeter weather stripping and mechanical interlocks close off gaps around aging frames, noticeably reducing cold-air infiltration.
Are these mounted on the inside or outside of the window?+
Our aluminum vertical models are designed for exterior mounting, which keeps the protective air gap between the storm panel and your primary window.
What is the best way to measure for vertical storm windows?+
Take width and height readings at three points across the opening, record the smallest figure for each, and reference our detailed measuring guide before placing your order.
